Chu Linyuan, the demon king of the Netherworld, was reborn as a concubine of an immortal sect. When he was munching on corpses in a mass grave, he bumped into his former enemy Shen Qingjue. The two people who were supposed to fight to the death were forced to form a twin life contract, but when they explored the devil's conspiracy to revive, they discovered that their souls were entangled with memories of three hundred generations of reincarnation.
When the Bone Erosion Curse resonates with the blood of the Burning Sky to create the power of chaos, when the Frostfall Sword pierces not only the chest but also the lies of heaven, the fallen Immortal Lord holds the blood-stained marriage contract, but the Crazy Demon Lord learns to trade his life for the common people. In this deadlock that spans time and space, the most poisonous poison is the black hair hidden in the sword tassel, and the sharpest edge is the heartbeat that has not cooled down after being reincarnated a hundred times.
